💡 Suggestions to Use / Tips
-
Keep the calculator on your study desk so it’s always within reach during lectures, homework or exam prep.
-
Make sure the protective cover is on when storing or carrying it around — this helps prevent damage to keys and display.
-
When working in statistical or engineering mode, use the dual‐line display to view both your formula input and result — this helps reduce errors.
-
For best results, keep batteries fresh-check before major use (exams); dim display may mean battery needs replacement.
-
Practice navigating the function keys ahead of time (e.g., trig, log, regression) so you’re comfortable using them under exam conditions.
-
Encourage a habit of clearing memory or unwanted results after each session to avoid carry-over errors.
-
Store in a cool, dry place and avoid exposure to extreme heat or direct sunlight to maximise lifetime.
